Lastly, iSeeCars also covered non-adopters on their study. As you can see on the list below, some states are taking a step back on green car adoption.

These states oppose the 48.4% national average increase, which is worth mentioning. Note that none of these states have any sort of state incentives for electric vehicles.

Arkansas: -27.0%

South Dakota: -23.9%

Oklahoma: -11.8%

South Carolina: -3.2%

New Mexico: -1.9%

What can we learn from those figures?

For the most part, this study shows an effective and positive adoption of green car vehicles in key states. When it comes to green car adopters, many of the top states have been running some sort of incentives.

Results also set price as one of the most important factors that impacts purchase.

That said, if those states with lower percentages of green car sales provide meaningful incentives to the adoption of green vehicles, more people will purchase them.
